What i ended up doing was i kept messing with it and adding new batteries untill i accidentally cleared the ram, but in doing so, i figured out what i did. we must have set the brightness up too much, and so the whole screen is white, so it looks like it is off. just press the on button and press second and hold the up arrow untill you can see something on your screen again.

It may be that your contrast is too light. turn the calculator on (it will not seem like it) then proceed to press the 2nd button then click the up button a few times to return to normal contrast.

Mine was acting up to. I found somewhere that the no/slow key response could be due to a short in the I/O socket. I blew into it really hard, and it worked perfectly after that. I hope this helps.

Dead Battery?


Take out the batteries. Also take out the backup battery. It is a button battery beneath the screw in the battery compartment. Check the button battery volts with a multi-meter. After 5 minutes put the button battery back in and then the fresh batteries. It might work now. Alternatively take out a battery, then hold the clear button and put the battery back in. Then try to turn on. If it still does not work take out a battery press the del button and put the battery back in.

Wont turn on


Just which steps have you gone through?

TI calculators have an annoying habit of dimming the screen when the batteries are changed so that it appears as if the calculator isn't turning on. Turn the calculator on (or at least press the ON key). Press and release the 2ND key. Press and hold the Up-arrow key for a few seconds and see whether the screen becomes legible.


If this doesn't do it, please reply to this post and we can go to the next step.

My screen turns on but when you do anything it has random numbers, line and letters on it and i need to get it fixed immediatley


I've had this issue before with my TI-83 Plus. I'm not sure exactly the solution I used, but these steps progress through the mildest to most extreme methods of fixing the calculator.


Solution 1: Take the batteries out.

Odds are you've tried this already, but it bears mentioning.

With the calculator on, remove the triple A batteries housed in the back. After a few seconds, replace them and turn the calculator on.


Solution 2: Clear the RAM.

Remove one of the AAA batteries. Press and hold the [CLEAR] key. While holding [CLEAR], reinsert the AAA battery and then turn the calculator on. The calculator should display the message "RAM Cleared". Release the [CLEAR] key and then press it one more time to remove the message.


Solution 3: Reinstall the operating system

Remove one of the AAA batteries. Press and hold the [DEL] key. While holding [DEL], reinsert the AAA battery and then turn the calculator on. The calculator should display "Waiting...Please install calculator software now"

Here is the website to reinstall your OS. First you'll need the TI-Connect software.


Solution 4: Remove all sources of power. This is a risky move, but if your calculator will absolutely not work after you try even reinstalling the operating system, it might be your last hope.

Remove all of the batteries including the round lithium battery for 5 minutes. After the 5 minute period, reinsert all of the batteries and turn the calculator on. Adjust the contrast if necessary.

Try a new set of batteries, also make sure that the battery contacts touch the batteries properly and that they are clean, if old batteries have leaked it may have corroded the contacts.

It won't turn on. I've put new batteries in 4months ago and it worked fine. And when school was over, I didn't used it all summer. But now when a new semister started, I needed to use my Calculator again...

Batteries drains quickly


I had something similar, it kept saying "battery low" after putting in new batteries. Try the Clear method; Take out one battery, hold the Clear button, while holding it insert the battery again and press on, and release. Now press clear again, turn it off and turn it back on again. If that doesn't help... well it must be something else... sorry :S
